Information on wiring
● If you are wiring your configuration, you must take into account the impact of cable length
on the supply voltage to the ET 200eco PN (permitted tolerance).
● The maximum infeed current of the terminal block is 10 A for 1L+ non-switched and 10 A
for 2L+ switched.
Do not exceed these values.
CAUTION
If you do not adhere to the maximum infeed currents and the cable cross-sections
required for these currents, you will risk overheating the cable insulation and contacts
resulting in damage to the device.
